Does anyone have any ideas what Rizzo may be announcing @ ekoparty?


BEAST: Surprising crypto attack against HTTPS

We present a new fast block-wise chosen-plaintext attack against SSL/TLS. We
also describe one application of the attack that allows an adversary to
efficiently decrypt and obtain authentication tokens and cookies from HTTPS
requests. Our exploit abuses a vulnerability present in the SSL/TLS
implementation of major Web browsers at the time of writing.
